How do I use the keys on my Nokia Internet Tablet?

A key press refers to the press and release of a key.
Some actions depend on the length of the key press.

• Power key (Located on the top center of the device.)
  - A short key press opens the Device mode dialog.
  A long key press turns the device on or off.
• Zoom keys (Located on the top left of the device.)
  - A short key press changes the zoom level of the current
  view, and adjusts the volume in audio applications.
• Full-screen key (Located on the top left of the
  device.) - A short key press switches between full s
  creen and normal screen modes.
• Escape key (Located on the front left of the device.)
  - A short key press removes the cursor from text
  fields, cancels menus and dialogs, and
  rejects confirmation notes.
  A long key press closes the
  topmost dialog or application view. In the Web browser this
  key acts as a back button.
• Application Switcher key (Located on the front left of the device.)
  - A short key press will display a list off the currently running applications.
  A long key press will switch the device to the Home view.
• Scroll keys (Located on the left side of the Integrated
  keyboard.) - A short key press moves the focus from
  one item to another in the respective direction. A long
  key press in the Web browser scrolls the content of the
  active page or frame. Press the center of the Scroll key
  to activate the item that has active focus, and to accept confirmation notes.
• Menu key (Located on the bottom left corner of the
  Integrated keyboard.) - A short key press opens and closes the application menu.
